That product may be cheaper at another store. Simply open its page to automatically check prices at over 80,000 stores and see them in ascending order. No tedious searches or setup are needed; just install it. You can also select a product name and right-click to check product information and reviews using AI. This extension eliminates a common online shopping regret: finding out later that another store offered a lower price. Just view a product page on Amazon or Rakuten as usual. It automatically searches over 80,000 stores on your behalf and tells you the lowest price for the product you are viewing. If it finds a cheaper store, a message appears at the bottom right of the screen saying, “A product is available for 〇 yen less.” Click it to see prices at other stores in ascending order in a browser side panel. There is no need to search again. After installation, just shop as usual. [Features] ■ Automatic lowest-price checks When you open a product page, the extension searches across other online stores and marketplaces and lists prices from lowest to highest. It matches JAN codes and model numbers to reduce the chance of listing different products. You can also choose in settings whether to include used items. ■ Compare effective prices including points and shipping Set your Rakuten Card type, Rakuten membership rank, Yahoo! Shopping payment method and other conditions once to compare effective prices including shipping and points and see which store offers the best deal. Your settings are used for calculations only in your browser and are not sent to the server. You can also compare displayed prices including shipping without considering points. ■ Choose a notification strip and side panel or a bar New users start with the notification strip and side panel. In settings, you can switch to a bar that lists other stores' prices at the bottom or top of the page. Existing users keep the bar they already use. ■ Favorites and recently viewed products You can revisit products you starred in the side panel and products you compared. They are saved only on your computer. ■ Right-click shopping search and AI research Select a product name or model number you find in news or on a blog, right-click and choose “Shopping search.” You can search for it on 価格なび and individual online stores. You can also research products with ChatGPT or Gemini. On pages where comparison is not active, you can also use “Consult AI” in the side panel. Both open a new tab with the selected or entered text only when clicked. ■ Automatically uncheck Rakuten newsletters Automatically turns off newsletter subscription checkboxes on the Rakuten Ichiba checkout page. This is enabled by default and can be disabled in settings. ■ Dismiss it quickly when it gets in the way The notification strip or bar can be closed with one click. You can also quickly turn automatic comparison itself on or off from the right-click menu. [Supported sites] Works on major Japanese online shopping sites, from large marketplaces such as Amazon, Rakuten Ichiba and Yahoo! Shopping to electronics retailers, home centers and manufacturers' official stores. Supported sites are continually checked and expanded. [Who is it for?] - People who find it troublesome to search other sites again and again - People who want to know which store really offers the best deal after points are included - People who want to install it in a less computer-savvy family member's browser; no further action is needed after installation [Information handled] - For comparison, we send the product name, model number, price, shipping cost, store name and similar information to our server (kakaku-navi.net) only when you open a product page on a supported shopping site. We do not collect browsing history from other pages. - We save product JAN codes to improve the accuracy of comparison results. These contain no personally identifying information. - We do not collect names, addresses, phone numbers, email addresses, login information, card numbers or similar information. - Point condition settings, favorites and recently viewed products are saved only on your computer and are not sent elsewhere. - For details, see the privacy policy: https://kakakunavi.jp/policy.html [About links] Links from comparison results to stores include affiliate links, such as Rakuten Affiliate and ValueCommerce. If you purchase through a link, we receive a referral fee, but your purchase price does not change. This revenue allows us to provide the service free of charge. There is no so-called “forced affiliate” behavior that makes a page view alone eligible for a referral fee. This happens only when you click a displayed link yourself. [Update history] 3.1.2 Corrected wording explaining display options on the settings page, side panel and right-click menu. Improved product model number detection to reduce cases where a different product is shown as cheaper, including dimensions in product names, game console names, and motor voltage and rotational speed. 3.1.1 Made it possible to close the side panel using the “×” at its upper right even in browsers such as Brave that do not have an “×” in the panel heading. - Prevented the side panel from remaining stuck on “Comparison is not available on this page” on pages that are not compared. - Added “How to use” to the top of the settings page and to the right-click menu. - Improved product model number detection to reduce cases where a different product is shown as cheaper, including award names, projector brightness and names of editions containing a year. 3.1.0 Added a notification strip at the bottom right when a cheaper store is found; clicking it opens details in the side panel. This is the initial display for new users; the previous bar remains available in settings. - Added favorites, recently viewed products and Consult AI to the side panel. Added an option in settings to compare displayed prices without considering points. - Improved product model number detection to reduce cases where a different product is shown as cheaper. 3.0.24 Improved product model number detection to reduce cases where a different product is shown as cheaper, including years in software names, memory and SD card standards, device models on smartphone case pages, and values with units such as vacuum suction power and communication speed. - Changed アイリスプラザ product pages to compare using the JAN code of the selected variant. 3.0.23 Fixed incorrect price readings at some stores, including セブンネット, XPRICE and コーナン. - Fixed an Amazon issue where unrelated inexpensive items such as cables could appear when no other store had a product with the same model number. - Added the current product page formats of モノタロウ and スクウェア・エニックス e-STORE to the comparison targets. - Removed stores that have closed, such as ポンパレモール, from the supported sites. - Changed “ヤフオク” in the right-click menu to its current name, “Yahoo!オークション.” 3.0.20 Changed the extension so configured point conditions, such as Rakuten Card rank, are not sent to the server, making it safer to use.
